A chemistry student wants to determine the specific heat capacity of a metal sample. The student adds 50 g of the metal sample to 200 g of water at 25°C in a calorimeter. The temperature of the water rises from 25°C to 38°C. Assume the specific heat capacity of water is 4.184 J/g°C. What is the specific heat capacity of the metal sample?

A chemistry student wants to determine the concentration of copper(II) ions in a solution using electrochemical methods. The student prepares a copper electrode and a reference electrode, and sets up a cell with the copper electrode immersed in the solution and the reference electrode in the salt bridge. The standard cell potential is measured to be +0.34 V. If the student knows that the reduction of copper(II) to copper occurs at the copper electrode, what is the concentration of copper(II) ions in the solution?
